Abstract

The invention discloses an orderly charging optimization scheduling method for electric vehicles based on the Logic-Benders decomposition algorithm. The specific steps are as follows: firstly, based on the mixed integer linear programming, the main model for selecting the charging mode of the electric vehicle is constructed; secondly, based on the constraint programming, the electric vehicle is constructed The charging timing optimization sub-model; finally, the main sub-model is iteratively solved using the Logic-Benders decomposition algorithm. On the premise of ensuring the user's charging demand, the present invention realizes the optimal economic efficiency of the electric vehicle charging scheduling system by selecting the charging mode of the electric vehicle and optimizing the charging sequence.

Description

Technical field [0001] The present invention relates to an orderly charging optimization scheduling method based on the Logic-Benders decomposition algorithm, which belongs to the field of electric vehicle's orderly charging technology. Background technique [0002] With the development of the electric motor industry and the promotion of related industrial policies, electric vehicles are rapidly increased. A large number of electric vehicles will cause the grid load to surge in a short time, bringing certain risks to the safe operation of the grid. Therefore, electric car ordered charging strategy is one of the current research hotspots. The purpose is to use actual effective economic or technical measures to control electric vehicles to charge the electric vehicle for charging, control electric vehicles for charging. Peak is filled, ensuring the coordinated interaction development of electric vehicles and grids. [0003] At present, the orderly charging research on electric vehi...
